[0001] The present invention relates to the technical field of projection equipment, and in particular to a motion prompting method and a projector. Background Art

[0002] Nowadays, more and more projectors are used in the home and education fields, and users may spend a lot of time watching movies during their rest time. However, for most users, they tend to maintain the same posture when watching movies, which can easily damage the eyesight, cervical spine, lumbar spine and other parts of the body. Although some users try to take the initiative to consciously pause and rest while watching movies, most users often find it difficult to maintain the habit of taking the initiative to rest and exercise when they are fully focused on watching movies.

[0003] Although a reminder video can be inserted into the video screen to remind users to take a break and exercise, the reminder video is too long and it is easy for users to forget the original viewing content, affecting the viewing experience. Summary of the invention

[0004] In order to solve the above technical problems, the present invention proposes a motion prompting method and a projector, which can not only realize motion prompting for local body parts, but also have little impact on the user's viewing experience.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] In a first aspect, the present invention discloses a motion prompting method, comprising the following steps:

[0007] Get the display duration of the current display screen;

[0008] When the display duration reaches a preset period, an exercise prompt video for a local body part is played in a preset area of ​​the display screen, and the playing duration of the exercise prompt video is within the prompt duration range.

[0009] Preferably, the acquisition of the display duration of the current display screen starts from when the projector is turned on and enters the main interface, or starts from each time the video playback is started.

[0010] Preferably, when the movement prompt video for a local body part is played in the preset area of ​​the display screen, the original screen content of the display screen is paused or keeps playing outside the preset area; the way in which the display screen keeps playing outside the preset area includes: the preset area covers the display area of ​​the original screen content; or the preset area is located at the edge of the display screen, and the display area of ​​the original screen content in the display screen is reduced and does not overlap with the preset area.

[0011] After playing the exercise prompt video for a local body part in the preset area of ​​the display screen, the method includes: after the exercise prompt video is played, closing the exercise prompt video in the preset area and continuing to display the original screen content of the display screen.

[0012] Preferably, the preset period is 10 minutes to 30 minutes, and the prompt duration ranges from 20 seconds to 60 seconds; and the playing duration of each motion prompt video is less than or equal to 1 / 10 of the preset period.

[0013] Preferably, playing the exercise prompt video for local body parts in a preset area of ​​the display screen when the display duration reaches a preset period includes: playing the exercise prompt video for local body parts in a preset area of ​​the display screen each time the display duration reaches a preset period.

[0014] Preferably, the two motion prompt videos played adjacently are targeted at different local body parts, and the local body parts targeted by the different motion prompt videos include the neck, waist, arms, and legs.

[0015] Preferably, when the display duration reaches a preset period, before playing the exercise prompt video for the local body part in the preset area of ​​the display screen, the method further includes:

[0016] Determine the playing time of the motion prompt video played each time according to the user's customized settings; and / or,

[0017] The play order of the movement prompt videos for different local body parts is determined according to the user's customized settings.

[0018] Preferably, when the display time reaches a preset period, playing an exercise prompt video for local body parts in a preset area of ​​the display screen includes: when playing the exercise prompt video in the preset area of ​​the display screen, also obtaining the user's body movements, and judging whether the user's body movements match the movements in the exercise prompt video; after playing the exercise prompt video for local body parts in the preset area of ​​the display screen, it includes: if the user's body movements match the movements in the exercise prompt video, then after the exercise prompt video is played, closing the exercise prompt video in the preset area and continuing to display the original screen content of the display screen.

[0019] Preferably, the preset area is smaller than the overall area of ​​the display screen, and after playing the exercise prompt video for local body parts in the preset area of ​​the display screen, the method includes: if it is determined that the user's body movements do not match the exercise prompt video, after the exercise prompt video is played, the exercise prompt video is expanded to the full screen of the display screen and played again, and the step of returning to determine whether the user's body movements match the exercise prompt video is returned.

[0020] In a second aspect, the present invention discloses a projector, comprising a processor and a memory, wherein the memory stores a computer program, and the computer program can be read by the processor to be executed to implement the steps of the motion prompting method as described in the first aspect.

[0021] Compared with the prior art, the beneficial effect of the present invention is that the exercise prompt method and projector proposed in the present invention can remind the user to exercise through multiple short exercise prompt videos after the user has watched the displayed image for a long time. This can not only realize exercise prompts for local body parts, but also has less impact on the user's viewing experience.

[0022] In a further solution, within a preset period, each video targets a different part of the body for exercise. In this way, users do not need to watch an entire long video covering the exercise of various parts of the body during the viewing process. Instead, they only need to watch a shorter video with exercise prompts for a single part at regular intervals. This can reduce the impact on the user's viewing experience and also achieve the purpose of exercising each part of the body in sequence. BRIEF DESCRIPTION OF THE DRAWINGS

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] like Figure 1 As shown, the first embodiment of the present invention discloses a motion prompting method, comprising the following steps:

[0033] S1: Get the display duration of the current display screen;

[0034] Among them, this method can be applied to display devices such as projectors and televisions, so the display screen can be divided into projection screen and TV screen. The following is an example of the application scenario of the projector. Get the projection time of the current projection screen, which is generally the boot time. For example, the timing can be started from the first time the projector enters the main interface after each boot, or it can also be started every time a video is played.

[0035] S2: When the display duration reaches a preset period, a motion prompt video for a local body part is played in a preset area of ​​the display screen, and the playing duration of the motion prompt video is within the prompt duration range.

[0036] The prompting method proposed in the present invention can remind users to exercise through multiple short-duration exercise prompting videos (for example, the prompting duration ranges from 20s to 60s, i.e., the playing duration of each exercise prompting video is controlled within 20s to 60s) after the user has watched the display screen for a long time. This can not only realize exercise prompts for local body parts, but also have little impact on the user's viewing experience. The exercise prompting videos for local body parts are generally multiple videos preset in the display device, and different videos target different parts of the body for exercise.

[0037] The shape of the preset area is generally a rectangle, but it can also be a common shape such as a circle or a square. When playing the motion prompt video for a local body part in the preset area of ​​the display screen, the original screen content of the display screen is paused or kept playing outside the preset area; the way in which the display screen keeps playing outside the preset area includes: the preset area covers the display area of ​​the original screen content, that is, the preset area will block part of the original screen content, at this time, the original screen content and the motion prompt video in the preset area are kept playing; or, the preset area is located at the edge of the display screen, and the display area of ​​the original screen content in the display screen is reduced and does not overlap with the preset area, for example, a corner area of ​​the display screen is used as the preset area, and the motion prompt video pops up to fill the preset area when the display time of the display screen reaches the preset period, and the original screen content that originally filled the full screen is reduced to a position connected to the preset area, such as the reduced original screen is connected to the top corner of the motion prompt video, at this time, the original screen content and the motion prompt video in the preset area are kept playing.

[0038] The following steps after step S2 include: after the motion prompt video is played, closing the motion prompt video in the preset area, and continuing to display the original screen content of the display screen, that is, continuing to play the original video content or returning to the original control interface.

[0039] The original screen content may be the screen content such as the operation interface, video, image, etc. that is being displayed on the display screen before the motion prompt video pops up.

[0040] In a further embodiment, the preset period is 10 minutes to 30 minutes; the prompt duration ranges from 20 seconds to 60 seconds, that is, the playing duration of each exercise prompt video is 20 seconds to 60 seconds; each playing duration of the exercise prompt video is less than or equal to 1 / 10 of the preset period, for example, if a reminder is given every 10 minutes of video playback, the playing duration of the subsequent exercise prompt video is within 1 minute. If the preset period is greater than 10 minutes, the playing duration of the exercise prompt video is also controlled within 1 minute to avoid the exercise prompt video being too long and affecting the user's viewing experience. If the exercise prompt video is too long, it is easy for the user to forget the original video content before the prompt.

[0041] In a specific example, when the display time of the picture reaches 0.25h, 0.5h, 0.75h, 1h... (every 15 minutes, that is, the preset period is 15 minutes), the current video progress or control interface is recorded, and a short-term exercise prompt video interface for a local body part is displayed separately in the corner of the picture to realize the picture-in-picture design, and the other areas of the display screen keep the original video content playing, or pause the original video content. Figure 2 In the display screen 100 , the original video interface 200 occupies the entire display screen 100 , the motion prompt video interface 300 is displayed in the upper right corner of the display screen 100 , and the display time 400 can also be displayed at the bottom of the display screen 100 .

[0042] In a further embodiment, each time the display duration reaches a preset period, an exercise prompt video for a local body part is played in a preset area of ​​the display screen, and N preset periods are a total preset period, and the exercise prompt video is repeatedly played with the total preset period as a period; wherein, the exercise prompt videos played each time in each total preset period are different or partially the same. Furthermore, the two adjacently played exercise prompt videos target different local body parts, and the local body parts targeted by different exercise prompt videos include the neck, waist, arms, and legs, so that exercise prompts can be fully provided for different body parts in multiple exercise prompt videos without affecting the viewing experience too much.

[0043] During the specific implementation process, the video display duration is determined according to the internal timing of the projection system, rather than simply relying on the video progress bar. This exercise prompt video interface lasts for 20 seconds to 1 minute, and each time the exercise prompt video interface content pops up, it only provides exercise prompts for one joint of the body, so that even in a short period of time, the part can be fully and effectively exercised. The exercise parts include the neck, arms, waist, and legs, that is, the interface content of each exercise prompt video provides prompts for one of the parts respectively. The interface of each exercise prompt video contains preset exercise instructions, such as turning the neck, pitching the head, turning the arms, twisting the waist, lifting the legs, etc. For example Figures 3 to 5 , for example, 1.5h is a total preset period, and the preset period is 0.5h, Figure 3 The video is shown as the first preset cycle of 0.5h. The exercise prompt video is for the neck. Figure 4 The following is a video showing the second preset cycle of 1 hour, where the exercise prompt video is for the waist. Figure 5 As shown, in the second preset cycle of 1.5 hours, the exercise prompt video is an exercise video for the legs. After the exercise prompt video for each part is played once, the next cycle can be entered and the timing can be restarted.

[0044] In a further embodiment, before step S2, it also includes: determining the playback duration of the motion prompt video each time according to the user's custom settings; and / or determining the playback order of the motion prompt videos for different local body parts according to the user's custom settings.

[0045] The duration of each appearance of the exercise prompt video interface can be customized by the user, and the order of appearance of the exercise prompt videos for each body part after each startup can also be customized by the user. The system calls the corresponding exercise prompt video based on the user's settings. For example, the user can select "neck, neck, waist, leg" in the system settings, and the first two prompt videos will be the exercise prompt videos corresponding to the neck.

[0046] These motion prompt videos can be downloaded in advance and built into the projector memory. When the screen display time reaches the corresponding time, the corresponding motion prompt videos are called in turn. Alternatively, after the user turns on the projection, the system loads the latest motion prompt video on the platform through the network background, and plays the motion prompt video when the system timing is reached. Alternatively, the user can place the selected motion prompt video into the projector or TV through APP, U disk, network disk, etc., and then the user customizes multiple playback intervals of the placed video. For example, the user can make multiple interval marks for different time positions of the placed video, and determine a playback interval between two adjacent interval marks; in one example, for a 2h video, the user can customize the 20min progress as the first interval mark, the 1h progress as the second interval mark, and the 1h30min as the third interval mark in a specific option; the way of customizing the interval mark allows the user to determine the motion reminder time by himself. The above-mentioned placed video is divided into several playback intervals based on the split segment, and the above-mentioned pop-up motion prompt video interface plays a playback interval of the placed video each time. Since the starting position and duration of the movements of various parts of the body in the exercise prompt videos uploaded by users themselves are different, this method allows users to flexibly adjust the playback interval to obtain reasonable exercise prompt video content.

[0047] In a further embodiment, the preset area is smaller than the overall area of ​​the display screen, and step S2 includes: when playing the motion prompt video in the preset area of ​​the display screen, also obtaining the user's body movements, and determining whether the user's body movements match the movements in the motion prompt video, and after step S2 includes: if the user's body movements match the movements in the motion prompt video, then after the motion prompt video is played, closing the motion prompt video in the preset area, and continuing to display the original screen content of the display screen; if it is determined that the user's body movements do not match the motion prompt video, then after the motion prompt video is played, expanding the motion prompt video to the full screen of the display screen and playing it again, and returning to the step of determining whether the user's body movements match the motion prompt video.

[0048] In the specific implementation process, the user's body movements can be captured and identified through an external camera device, where the external camera device can be a camera on a TV or a camera in front of an ultra-short-throw projector. During each playback of the motion prompt video interface, if the camera recognizes that the corresponding part of the user has completed the corresponding movement, the motion prompt video interface will automatically disappear after the duration. If the user does not complete the corresponding action as required, the motion prompt video interface that was originally displayed only in the corner can be expanded to full screen and played again, pausing the video content in the original display screen, while continuing to identify whether the user has completed the corresponding action.
